A Close Look at Speedmaster's Roller Rockers

Do you plan on putting these into service any time soon?
I putting together a build now with a '71 360 block and it's probably going be a 408 with good street manors I'm haven't decided yet. Either way it may be a while till it all comes together. It's all comes down to money and time. Anyone in NC want to help with that (the time part)?
